The iPod Photo Cache folder keeps getting created inside subfolders where it makes no sense, and I am looking for a way to correct this.

Here is the folder structure.

I have a Pictures folder.
Inside are many subfolders.
2 of these subfolders are named iPhone & iPad
via iTunes, my iPhone is set to sync photos inside the iPhone folder
via iTunes, my iPad is set to sync photos inside the iPad folder
the iPhone & iPad folders both have the iPod Photo Cache folder inside them, which is correct; the folder should be there.

However, other subfolders inside my Pictures folders (including the root) keep getting the iPod Photo Cache folder created; not all subfolders get it, just some. No iOS devices sync to these subfolders, so the Cache folder should not be appearing inside them.
